      hwmon: (max31785) Add OF device ID table · 98b16a09
      Javier Martinez Canillas authored
      The driver doesn't have a struct of_device_id table but supported devices
      are registered via Device Trees. This is working on the assumption that a
      I2C device registered via OF will always match a legacy I2C device ID and
      that the MODALIAS reported will always be of the form i2c:<device>.
      
      But this could change in the future so the correct approach is to have an
      OF device ID table if the devices are registered via OF.
      
      Before this patch:
      
      $ modinfo drivers/hwmon/pmbus/max31785.ko | grep alias
      alias:          i2c:max31785a

      After this patch:

      hwmon: (ina2xx) Make calibration register value fixed · 5d389b12
      Maciej Purski authored
      Calibration register is used for calculating current register in
      hardware according to datasheet:
      current = shunt_volt * calib_register / 2048 (ina 226)
      current = shunt_volt * calib_register / 4096 (ina 219)
      
      Fix calib_register value to 2048 for ina226 and 4096 for ina 219 in
      order to avoid truncation error and provide best precision allowed
      by shunt_voltage measurement. Make current scale value follow changes
      of shunt_resistor from sysfs as calib_register value is now fixed.
      
      Power_lsb value should also follow shunt_resistor changes as stated in
      datasheet:
      power_lsb = 25 * current_lsb (ina 226)
      power_lsb = 20 * current_lsb (ina 219)

      hwmon: (pmbus/max31785) Add dual tachometer support · cf583b42
      Andrew Jeffery authored
      The dual tachometer feature is implemented in hardware with a TACHSEL
      input to indicate the rotor under measurement, and exposed on the device
      by extending the READ_FAN_SPEED_1 word with two extra bytes*. The need
      to read the non-standard four-byte response leads to a cut-down
      implementation of i2c_smbus_xfer_emulated() included in the driver.
      Further, to expose the second rotor tachometer value to userspace the
      values are exposed through virtual pages. We re-route accesses to
      FAN_CONFIG_1_2 and READ_FAN_SPEED_1 on pages 23-28 (not defined by the
      hardware) to the same registers on pages 0-5, and with the latter command
      we extract the value from the second word of the four-byte response.
      
      * The documentation recommends the slower rotor be associated with
      TACHSEL=0, which corresponds to the first word of the response. The
      TACHSEL=0 measurement is used by the controller's closed-loop fan
      management to judge target fan rate.

      hwmon: (pmbus) Add virtual page config bit · 464df6fa
      Andrew Jeffery authored
      Some circumstances call for virtual pages, to expose multiple values
      packed into an extended PMBus register in a manner non-compliant with
      the PMBus standard. An example of this is the Maxim MAX31785 controller,
      which extends the READ_FAN_SPEED_1 PMBus register from two to four bytes
      to support tach readings for both rotors of a dual rotor fan. This extended
      register contains two word-sized values, one reporting the rate of the
      fastest rotor, the other the rate of the slowest. The concept of virtual
      pages aids this situation by mapping the page number onto the value to be
      selected from the vectored result.
      
      We should not try to set virtual pages on the device as such a page
      explicitly doesn't exist; add a flag so we can avoid doing so.

      Andrew Jeffery authored
      The implementation makes use of the new fan control virtual registers
      exposed by the pmbus core. It mixes use of the default implementations
      with some overrides via the read/write handlers to handle FAN_COMMAND_1
      on the MAX31785, whose definition breaks the value range into various
      control bands dependent on RPM or PWM mode.

      hwmon: (pmbus) Add fan control support · d206636e
      Andrew Jeffery authored
      Expose fanX_target, pwmX and pwmX_enable hwmon sysfs attributes.
      
      Fans in a PMBus device are driven by the configuration of two registers,
      FAN_CONFIG_x_y and FAN_COMMAND_x: FAN_CONFIG_x_y dictates how the fan
      and the tacho operate (if installed), while FAN_COMMAND_x sets the
      desired fan rate. The unit of FAN_COMMAND_x is dependent on the
      operational fan mode, RPM or PWM percent duty, as determined by the
      corresponding configuration in FAN_CONFIG_x_y.
      
      The mapping of fanX_target, pwmX and pwmX_enable onto FAN_CONFIG_x_y and
      FAN_COMMAND_x is implemented with the addition of virtual registers to
      facilitate the necessary side-effects of each access:
      
      1. PMBUS_VIRT_FAN_TARGET_x
      2. PMBUS_VIRT_PWM_x
      3. PMBUS_VIRT_PWM_ENABLE_x
      
      Some complexity arises with the fanX_target and pwmX attributes both mapping
      onto FAN_COMMAND_x: There is no general mapping between PWM percent duty and
      RPM, so we can't display values in either attribute in terms of the other
      (which in my mind is the intuitive, if impossible, behaviour). This problem
      also affects the pwmX_enable attribute which allows userspace to switch between
      full speed, manual PWM and a number of automatic control modes, possibly
      including a switch to RPM behaviour (e.g. automatically adjusting PWM duty to
      reach a RPM target, the behaviour of fanX_target).
      
      The next most intuitive behaviour is for fanX_target and pwmX to simply be
      independent, to retain their most recently set value even if that value is not
      active on the hardware (due to switching to the alternative control mode). This
      property of retaining the value independent of the hardware state has useful
      results for both userspace and the kernel: Userspace always sees a sensible
      value in the attribute (the last thing it was set to, as opposed to 0 or
      receiving an error on read), and the kernel can use the attributes as a value
      cache. This latter point eases the implementation of pwmX_enable, which can
      look up the associated pmbus_sensor object, take its cached value and apply it
      to hardware on changing control mode. This ensures we will not arbitrarily set
      a PWM value as an RPM value or vice versa, and we can assume that the RPM or
      PWM value set was sensible at least at some point in the past.
      
      Finally, the DIRECT mode coefficients of some controllers is different between
      RPM and PWM percent duty control modes, so PSC_PWM is introduced to capture the
      necessary coefficients. As pmbus core had no PWM support previously PSC_FAN
      continues to be used to capture the RPM DIRECT coefficients, but in order to
      avoid falsely applying RPM scaling to PWM values I have introduced the
      PMBUS_HAVE_PWM12 and PMB_BUS_HAVE_PWM34 feature bits. These feature bits allow
      drivers to explicitly declare PWM support in order to have the attributes
      exposed.

      pci_get_bus_and_slot() is restrictive such that it assumes domain=0 as
      where a PCI device is present. This restricts the device drivers to be
      reused for other domain numbers.
      
      Use pci_get_domain_bus_and_slot() with a domain number of 0 where we can't
      extract the domain number. Other places, use the actual domain number from

       "A rather large update after the kaisered maintainer finally found time
        to handle regression reports.
      
         - The larger part addresses a regression caused by the x86 vector
           management rework.
      
           The reservation based model does not work reliably for MSI
           interrupts, if they cannot be masked (yes, yet another hw
           engineering trainwreck). The reason is that the reservation mode
           assigns a dummy vector when the interrupt is allocated and switches
           to a real vector when the interrupt is requested.
      
           If the MSI entry cannot be masked then the initialization might
           raise an interrupt before the interrupt is requested, which ends up
           as spurious interrupt and causes device malfunction and worse. The
           fix is to exclude MSI interrupts which do not support masking from
           reservation mode and assign a real vector right away.
      
         - Extend the extra lockdep class setup for nested interrupts with a
           class for the recently added irq_desc::request_mutex so lockdep can
           differeniate and does not emit false positive warnings.
      
         - A ratelimit guard for the bad irq printout so in case a bad irq
           comes back immediately the system does not drown in dmesg spam"

      x86/ldt: Plug memory leak in error path · a62d6985
      Thomas Gleixner authored
      The error path in write_ldt() tries to free 'old_ldt' instead of the newly
      allocated 'new_ldt', resulting in a memory leak. It also misses to clean up a
      half populated LDT pagetable, which is not a leak as it gets cleaned up
      when the process exits.
      
      Free both the potentially half populated LDT pagetable and the newly
      allocated LDT struct. This can be done unconditionally because once an LDT
      is mapped subsequent maps will succeed, because the PTE page is already
      populated and the two LDTs fit into that single page.

      x86/mm: Remove preempt_disable/enable() from __native_flush_tlb() · decab088
      Thomas Gleixner authored
      The preempt_disable/enable() pair in __native_flush_tlb() was added in
      commit:
      
        5cf0791d ("x86/mm: Disable preemption during CR3 read+write")
      
      ... to protect the UP variant of flush_tlb_mm_range().
      
      That preempt_disable/enable() pair should have been added to the UP variant
      of flush_tlb_mm_range() instead.
      
      The UP variant was removed with commit:
      
        ce4a4e56 ("x86/mm: Remove the UP asm/tlbflush.h code, always use the (formerly) SMP code")
      
      ... but the preempt_disable/enable() pair stayed around.
      
      The latest change to __native_flush_tlb() in commit:
      
        6fd166aa ("x86/mm: Use/Fix PCID to optimize user/kernel switches")
      
      ... added an access to a per CPU variable outside the preempt disabled
      regions, which makes no sense at all. __native_flush_tlb() must always
      be called with at least preemption disabled.
      
      Remove the preempt_disable/enable() pair and add a WARN_ON_ONCE() to catch
      bad callers independent of the smp_processor_id() debugging.

      x86/smpboot: Remove stale TLB flush invocations · 322f8b8b
      Thomas Gleixner authored
      smpboot_setup_warm_reset_vector() and smpboot_restore_warm_reset_vector()
      invoke local_flush_tlb() for no obvious reason.
      
      Digging in history revealed that the original code in the 2.1 era added
      those because the code manipulated a swapper_pg_dir pagetable entry. The
      pagetable manipulation was removed long ago in the 2.3 timeframe, but the
      TLB flush invocations stayed around forever.
      
      Remove them along with the pointless pr_debug()s which come from the same 2.1
      change.
